The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 (R167259420) is a state-of-the-art ball runner block designed for high precision and durability in linear motion applications. This component is part of the Ball Rail Systems line, specifically crafted to handle high torsional moments on rails where lateral space may be restricted. The runner block body is made from unalloyed steel CS and comes without a ball chain, featuring a compact width (CNS format), normal length, and standard height. With an accuracy class N (standard) and a preload class C (preload-free), the B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 ensures consistent performance without pre-tensioning. It boasts excellent dynamic characteristics, including optimized entry-zone geometry for reduced elastic deflection and an integrated all-around sealing system for protection against contaminants. The product also offers improved rigidity under lift-off and side-loading conditions thanks to two central additional mounting screw holes. This model can be used interchangeably with all BNS ball guide rails, enhancing flexibility in design configurations. Furthermore, it comes with initial lubrication and preservation for long-term maintenance-free operation. Designed to support attachments from above, the runner block provides an end-face fastening thread for various attachments while maintaining maximum system rigidity through its preloaded O-arrangement. The B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 is ideal for applications requiring high load ratings in all four main loading directions, as well as those that benefit from long-term lubrication over several years. Its dynamic load capacity and torsional moment load capacity are determined as per DIN ISO standards, ensuring reliable performance even under demanding conditions. The product's design also facilitates self-alignment to compensate for potential misalignments during installation or operation. In summary, this Bosch Rexroth ball runner block is engineered to provide very high torsional moment load capacity and resistance, making it especially suitable as an individual guide in various industrial linear motion systems.
